Abstract: SmartStax is a new biotechnology-derived corn product. It combines the VT Triple Pro®  technology of Monsanto Company and the Herculex technology of Dow Chemical Company, with a total of eight different insect-resistant and herbicide-tolerant genes. It serves as an excellent example of applying gene stacking technologies to provide new tools for comprehensive insect resistance management. This article will briefly review the gene stacking or trait stacking technologies applied in the product, as well as some basic concepts of the integrated insect resistance management.
